Control Method
Open-loop control：At the start time, the locally config-
ured active instruction is sent to the power output port of
the inverter, thereby implementing active power control.
Closed-loop control:
• In case no Smart Energy Meter is selected, at the
beginning time, the active instruction configured lo-
cally is used as target value, and active power com-
pensation ratio is calculated and sent to the power
output port of the inverter. Generally, this strategy is
used for fast and accurate active power regulation.
• In case a Smart Energy Meter is selected, at the be-
ginning time, active instruction configured locally is
used as target value, active power of the meter
needs to be collected and used as input parameter,
and active power compensation ratio is calculated
and sent to the power output port of the inverter.
Generally, this strategy is used for anti-backflow or
avoiding zero power feed-in.

Power Limit in Case of Meter
Communication Anomaly (%)*
In the event of meter communication failure, set a fixed
proportion to limit the power fed into the grid.
Wiring mode*
Direct connection: One Logger1000 is connected to all
inverters, where all the inverters must be string inverters
or central inverters.
Cascading: Multiple Logger1000 are cascaded, and
this Logger1000 is used as the host.
Start after communication re-
covery *
Enable: After the Smart Energy Meter recovers normal
communication, the Logger1000 will deliver start instruc-
tion to the inverter.
Disable: After the Smart Energy Meter recovers normal
communication, the Logger1000 will not deliver start in-
struction to the inverter.
Start delay after communica-
tion recovery *
After the Smart Energy Meter recovers normal commu-
nication, the Logger1000 will deliver start instruction to
the inverter.
Parameter range: 0~120s
